cation, reference being had therein to the accompanying drawing.

This invention relates to furnaces, particularly designed for conveying and heating plates for sheet tin and black plate mills.

The primary object of this invention is to i combine a plate' heating furnace with a pair furnace whereby a saving of labor and fuel will be accomplished.

Another object of this invention is to provide a furnace that can be ily fired to produce a uniform heat throughout the plate heating furnace, and thereby obtain a' high grade of work without damaging the iron or producing a waste product. y

A further object of this invention is to provide a novel furnace in which pairs of billets can be thoroughly heated, and the heat from said furnace utilized for heating packs or sheets of iron, and by the novel distribution of heat Within the plate heating furnace and within the pair furnace, the billets are prevented froin scaling and are properly heated preparatory to rolling.

A still further object of this invention is to' combine furnaces in such manner that a cessation in the operation of the furnace will not interfere with the adjoining furnaces.

A still further object of this invention is to provide a furnace for continuously heating packs of plates, a novel conveyer being used for this purpose, which supports the packs of plates whereby they will be evenly subjected to the heat Within the furnace and produce a better quality of goods.

With the above and other objects in view which will more readily appear as the inven tion is better understood,the same consists in the novel construction, combination and arrangement of parts to be hereinafter described, a'nd then specifically pointed out in the appended claims.

Referring .to the drawings: Figure 1 is a side elevation of a furnace, Fig. 2 is a plan of the same, partly in section, Fig. 3 is a longitudinal sectional 'view of a furnace, Fig. Ll is a rear end view of the same, Fig. 5 is a view of the front end of a furnace,- Fig. 6 is a cross sectional view, taken on the line Vl--Vl of Fig. 1, Fig. 7 is a similar view taken on the line VII-VH of Fig. 1, Fig. S is an elevation `of a portion of a horizontal conveyer, Fig. 9 1s a cross sectional view of the same, Fig.` l() 60 is an elevation of a portion of an inclined conveyercarrier, and Fig. 11 is a plan of the same. l

In the accompanying drawings, l and 2 designate what l have termed pair fury naces, these furnaces adjoining one another, and an oblong plate heating furnacev 3 through which the plates are conveyed in a manner as hereinafter referred to. i The furnaces 2 are constructed with bridge walls 4;, 70`

grates 5, and fire doors 6, whereby fires can be built upon the grates 5 and fed from the exterior of the furnaces. The furnaces are also rovided with openings 7 normally close permitting of billets being placed in the furnace, preferably in pairs, tov be heated. Smoke, gas, and products of combustion, are carried from the furnaces 1 and -2 through.-

opening 9, these openings being closed by vertically disposed gates 10 connecting with bell-crank levers 1 1, pivotally mounted upon the top of the furnace 3, as at 12, said levers connecting with cables 14, suspended from the side of the furnace 3, opposite the fur- 85 naces 1 and 2.

ln using the gates 10 l can close the furnace 3 when it is desired to make repairs or alterations, and in order that the same can bef accomplished with the furnaces 1 and 2, and 90 still maintain the furnace 3 in operation, l provide auxiliary grate bars 15 at the ends of the furnace 3, fires being built upon said grate bars at any time it is desired to operate` the furnace 3 and the pendant of the furnaces 95 1 and 2 or to increase the heat Within the furnace 3.

The products of combustion or the heated air entering the furnace 3 through the openings 9 escapes at the ends of the furnace 3 160 through openings 16 into longitudinally disposed lues 17, communicating with a stack or chimney 18, located centrally of the fur nace3. The openings 16 are closed by slides,

operated through the medium of pivoted levers 2O and carried by the side of the furnace 3 at the ends thereof. The outer ends of the slides 19 are provided with openings, to lreceive the pperends of the levers 20.

In constructing the furnace 3, l use eyebeams 21 carrying inwardly projecting plates 22 for supp @ting-.confronting channehshaped by balanced doors 8, these openings 75 guides 23, said guides being provided with longitudinal grooves 24. Adapted to slide in the guides 23 are conveyer plates 25, provided with depending lugs 26 to ride in the grooves 24 of the guides. The plates'26 are carried by an endless sprocket chain 27 traveling over sprocket wheels 2S, arranged at the ends of the furnace 3, these sprocket wheels being suitably driven, and for clearness of illustration, are illustrated diagrammatically in Fig. 1 of the drawings. Each conveyer plate is provided with a socket 29 and With a depending stem 30 of a conveyer frame 31, each frame having detachable pins 32 and a catch pin 33, the latter being of`a greater height than the former. The pins 32 are adapted to support plates or a pack of plates and in being elevated above the frame 31 they pass through the furnace 3, these plates will be subjected to heat upon all sides.

In practice, the plates are carried throu h the furnace from the front end thereof t0 t e rear end thereof, and in order to yconvey the plates to the front end of the furnace from the rear end thereof, I employ an inclined conveyer 34. This conveyer is`cor tructed of suitable driven sprocket wheels 36, endless chains 37, having outwardly extending carriers 38. The conveyer 34V extends from the rear end of the furnace 3, at one side thereof, upwardly at an angle to said furnace, passingover sprocket Wheels suitably supported above the furnace, and other sprocket wheels located at the front 'end of the furnace 3, and suitably supported Vin the metallic casing 39, containing an inclined plate 40, upon which packs of plates are delivered, from where the plates slide downwardly upon the plate 3,2, said plate being slotted to permit of the catch pins 33 passing therethrough to engage a plate.r

In close proximity to the rear end of said conveyer is arranged an adjustable table 40a upon which plates are placedto be engaged by the carriers 38, and conveyed to the front end of the furnace.l Another adjustable table 40h is located adjacent to the conveyer, th'is table being employed for supporting plateseither to be placed upon the tablev 10a or carried to rolls.

l `or removing the packs of plates from the horizontal conveyer, after they have passed through the furnace 3, I arrange a plurality of delivery rails '-12 at the rear end of the furnace and an endless chain 43, driven from a suitable lsource of energy. lThe .chain 43 carries kickers '-14 to engage the packs of plates and move the saine to the delivery from where they slide downwardly.

it the front and rear ends of the furnace, l use hinged doors 4G for normalljr closing the openings through which the horizontal conveyor passes, these doors swinging whenever the plates and frames of said conveyer passes into the furnace 3. In lieurof these hinged doors I can use doors that are manually elevated, said doors being particularly designed for closing the furnace while the temperature is being raised therein.

It is though that those skilled in the art of manufacturing plates will readily realize the many advantages of my improved combined and continuous furnace, and I desire it to be understood that such structural changes as are permissible by the appended claims can 'be resorted to without departing from the spirit and scope of the invention.

Having now described my invention, what I claim as new, is:-

l. A.' furnace consisting of an oblong structure having longitudinally disposed flues inits top terminating in a stack, adjoining pairing furnaces-located at one side of said structure and communicating therewitlj',
